Chris Metcalf | c539914 | 2013-05-02 15:29:04 -0400 | [diff] [blame] | 362 | Since MDE 4.2, the Tilera hypervisor runs the kernel |
| 363 | at PL2 by default. If running under an older hypervisor, |
| 364 | or as a KVM guest, you must run at PL1. (The current |
| 365 | hypervisor may also be recompiled with "make HV_PL=2" to |
| 366 | allow it to run a kernel at PL1, but clients running at PL1 |
| 367 | are not expected to be supported indefinitely.) |
| 368 | |
| 369 | If you're not sure, don't change the default. |
